WINDOW-GLASS-DRAWING MACHINE.

Specification of Letters Patent. Patented Man" 8, 1910.

Application filed March 30, 1909. Serial No. 486,677.

To all whom it may concern:

Be it known that I, CHARLIE M. RnssLAR,

a citizen of the United States,residing at 'Jeannette, in-the county of lVestmoreland and State of Pennsylvania, have invented a new and useful Improvement in \Vindow- Glass-Drawing Machines, 0f.,whih the fol lowing is a pecitication.

This in've tion. relates to a continuous window glass drawing machine, the object of the invention being to provide a machine which is so constructed that the glass cylin' ders now manufactured for forming window glass can'be formed continuously so as "to overcome the difiicultles now existing of having to repeat the operation of forming a new cylinder after the same has been drawn to the desired length. I

A still further object of the invention is to provide means for supporting the cylinder, said means comprising conveyers so that the same will be securely held whereby the plungercarried by the air pipe can be lowered into the same so that the cylinder can be'moved upwardly and y repeatin this operation a continuous cylinder. W51 be formed it of [course being understood that the upper end of the cylinder is cracked off into the desired lengtl.

Another object ()filic invention is to p'rocylinders are formed and, mounted on a latform C arranged to one ,side of the uprights vide the air pipe with a forming bait which is adapted to be lowered into the vessel containing the molten glass, said air pipe having a piston which is adapted tobe forced downwardly into the cylinder after the bait.

has been removed whereby the air can be i forced into the cylinder in the same manner,

said cylinder being held whilethis operation is being performed by arms carried by the endless conveyers A. still further object of the invention is to provide a spring actuated piston formed of two'sections which are so. mounted that they are adapted to adjust themselves to the size of the glass cylinder so as to form an air tight joint.

A still further object of the invention is to provide novel means for operating the de vice whereby the conveyers areso geared and connected together that-the arms will strike the opposite sides of the glass eylin 'dcr at the same time in such a manner that all danger of the cylinder being broken is prevented.

\Vith these objects in View, my invention consists of the novel features of construction, combination and arrangement 'ofpalrts hereinafterfully described, pointed-out in the claims and shown in the accompanying drawings, in which,

.Figure- 1 is a side elevation of 'my similar View showing the nippledetached and the air pipe carrying the piston forced improved machine showing the cylinder down into thecylinder so that the cylinder portion of the same can be cracked off and removed so as to form window glass. Fig. 3 is a section taken online 3 -3 of Fig. 1.

can be drawn upwardly whereby the upper,

Fig. 4 is a' top plan view ofr my improved piston showing the air pipe in, section and, s

Fig. 5 is a vertical section through the air pipe and' piston.

In carrying out my improved invention, I employ a frame A formed of four u ri hts which are adapted to be arranged WIth-III a building, the upri hts being of such a length that they-.wille end-above the first floor o-f'the same upon which theglass cylinders. are removed after they have been cracked off as will be hereinafter fully described.

Arranged between the uprights on thebqttom floor of the building is aftank 'B. adapted to contain moltei'i; glass from which the is an engine D foridriving a fan E providedwith a conducting pipe F whichis connected. to a vertical pipe G arranged between the uprights at their upper ends in whichis slid-: ably mounted an air pipe H which is proe vided, witha bait'I carried by a stem 1" which is screw threaded onth'elower end of the air pipe H so that item be readily detached, said bait being adapted .to be lowform a cylinder when the same is drawn upwardly it of course being understood that air is being forced into thesame at the same tir c this being the ordinary manner of ered into the tank of molten glass sofas 'to I forming a glass cylinder and is only given so i that the operation of my improved machine can be readily understood.

-Mounted between the uprights are en less" conveyers J which work oversp'rocket chains carried by shafts J and J whichare pro-- vided with pulleys over which passes a twisted belt K 50 that the same'will bermovedin a plurality of curved'arms L ad dgt unison, said conveyersbeing .provided'withj with abeveled ear M which meshes with a beveled gear hi carriedby a power shaft M which is drivenby the engine through the medium of a reducing gear not shown whereby the same can be readily started and stopped by controlling the engine so Mounted on the air pipe H 'is; a conical one another and connected to theair pipe H that the cylinder can be held many position piston N formed of two sections overlapping by bowed springs N which normally hold the sections/apart so that when the same are forced into a, glass cylinder they will yield sufficiently to allow the same to be moved downwardly within the cylinder and at the same time the springs are strong enough to "force the sections of the piston outwardly so as to form an air tight joint around the same. The pipe H works through a gage mounted bet-ween the uprights so that the upward movement-0f the cylinder can be 1 controlled and will'be seen that'by' removing the bait I from the air pipe after the cylinder has been drawn upwardly into the position shown and forcing the piston I down into/the cylinder andat the same time startingthe engine so as to cause the cylinder to be moved upwardly by the conveyers it of" course being understood that air is being forced into the cylinder by the air pipe at the same time, the cylinder is drawn upwardly so that the upper end of the same can be readily cracked of]? horizontally and then vertically so that the cylinder can be removed from around the pipe II as shown in Fig. 2 and by repeating this operation the cylinder can be drawn continuously when-the piston-is being forced into the cylinder and when the cylinder isbeing cracked 0d at its upper end it'will be seen that by this construction after the cylinder is oncestarted by the temporary bait used a conisthe case with machines of this character nowin use.

The operatmn of the machine is as follows: The vair pipe carrying the temporary 'bait is lowered into the tank of molten glassv and as the same is raised upwardly by any suitable means not shown and air is forced into the same the cylinder is started and as "it reaches the arms of the conveyers it is embraced bythe sameand carried upwardly intothe position shown in Fig. l which brings the upper end ,of the cylinder in line "with the second floor of the building so that "the tempor ry. bait can be readily unscrewed under from the air pipe it of course bein stood that the same is cracked o of the upper end of the'cylinder in the ordinary manner. The .piston carried by the air pipe .1 then forced down into the cylinder and the engine started'so as tocause the cylinder to be drawn upwardly and when it has reached asuflicient length the upper end is.

cracked off and theoperation repeated.

While I have shown and described specific means for raising the cylinder it is of course understood'that various other means can be employed'without departing from the spirit of my invention. 7

In a continuous glass drawing machine the combination with an air pipe, a piston carried by said air pipe and means for raising a glass cylinder after the cylinder has been started." v y 2.
